  Science

  11 Nov 2020 | Environ Sci Technol

  PFOS distributed on specific sizes exhibited seasonal and regional dependency, while no such patterns were observed for PFOA.

• Association between per and polyfluoroalkyl substances and markers of inflammation and oxidative stress

  Science

  10 Nov 2020 | Environ Res.

• Occurrence and Distribution of Per- and Polyfluoroalkyl Substances in Tianjin, China: The Contribution of Emerging and Unknown Analogues

  Science

  10 Nov 2020 | Environ Sci Technol .

  Field-derived sediment-water distribution coefficients of emerging PFAS are provided for the first time, confirming that cationic and zwitterionic PFASs tend to be strongly associated with sediments.

• Associations between six common per- and polyfluoroalkyl substances and estrogens in neonates of China.
